Evaluate: 2 × {17 - 2 × (10 - 5)}
14
To evaluate the expression 2 × {17 - 2 × (10 - 5)}, we need to follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Here's the step-by-step process:
- Simplify expressions inside the parentheses first:
- The innermost parentheses is (10 - 5). Calculate: 10 - 5 = 5.
- Substitute the result back into the expression: 2 × {17 - 2 × 5}.
- Next, perform the multiplication:
- Calculate 2 × 5 = 10.
- Update the expression: 2 × {17 - 10}.
- Now perform the subtraction:
- Calculate 17 - 10 = 7.
- Update the expression with the new result: 2 × 7.
- Finally, perform the multiplication:
- Calculate 2 × 7 = 14.
The evaluated result of the given expression is 14.
